摘　　要：结合仿生矿化的方法,利用牛血清白蛋白LB膜为模板经过低温退火后在FTO(SnO2∶F)导电玻璃上制备了大面积连续致密的多孔ZnO薄膜。经SEM、XRD、荧光光谱仪和紫外可见吸收光谱仪等测量手段,分析了ZnO薄膜样品的表面形貌、结晶性能以及光致发光特性。实验证明该方法简单快捷,适于大面积生产,且制备的薄膜样品的生长具有高比表面积和在近紫外范围的宽带发光特性。Large area,uniform and porous ZnO thin films were fabricated below a BSA monolayer annealed at low temperature on FTO substrates by using biomimetic method.The microstructure,surface topography,crystallization properties and photoluminescence properties of the obtained ZnO thin films were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD)and ultraviolet visible(UV-Vis)absorption spectroscopy and photoluminescence spectroscopy(PL).The results show that the simple and fast preparation is suitable for large area production.The results of characterization indicate that the thin films have high specific surface area and broadband luminescence properties of violet light.
